Session 3 at SOAR by Avembsys

An interesting session by our SME which included aerodynamic basics,terminology,aircrafts.
       The session started with the discussion of EMP (Electromagnetic pulse) and electronic warfare.In this ever contending world,its a race for dominance in every field.Electronic warfare can be understood through an example that is if a missile is launched,the opponent can detect this with the help of radar.In order to suppress this advantage of detection,if a EMP is sent disabling the radar the attack is imminent.This technique can be used to attack an enemy or impede enemy assaults.
        Our SME introduced us to aerodynamic basics.We had a flashback of elementary physics and physical quantities like momentum, density, temperature, viscosity, pressure etc.We even travelled back to chemistry such as the three gas laws and isothermal and adiabatic processes.Various terms related to aeronautics was summarised.Terms like altitude, attitude, center of gravity, aerodynamic center, mach number etc.
        Next we were shown with a picture of a aircraft and asked to observe what we see.This led to the discussion of how do aircrafts fly? The flight is produced due to thrust formed by jet engines and the design of wings which leads to differential pressure on the two faces which led to lift.
        The various parts of an air craft was shown to us.The parts such as cockpit, jet engine, fuselage, wings, vertical stabilizer and horizontal stabilizer.The spoilers, slats, aileron, flaps, rudder and elevator facilitates the six degrees of freedom of an aircraft in turn helps the maneuvering of the huge metal in air.
        This informative session ended with assignments and a video regarding the investigation of Air France 296 crash in 1988.
